Answer: 336.14 cm²
Step-by-step explanation:
To find the area of the rectangle after being cut, we want to find the area of the two semicircles and subtract it from the area of the rectangle. The area of the rectangle is just base times height, or 35cm times 14cm = 490cm² . Since there are two semicircles with the same diameter, we can just solve for the area of a circle and subtract it. To find the area of the circle, we need the radius, which we get by dividing the diameter by 2. After that, we calculate the radius to be 7cm, squared and multiplied by 3.14 (area of a circle) to get 153.86 cm². Subtract the areas, and we get 490 - 153.86 = 336.14 cm²
P is just a variable in this equation
Answer:

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

So then we need to replace the value of x =3 and we got:

Step-by-step explanation:
For this case we have the following function:

Where x represent the number of period of times of 22 minutes. If we want to know the value of the population after 66 minutes we need to find the value of x on this way:

So then we need to replace the value of x =3 and we got:

Answer:
(4x+1)^2
Step-by-step explanation:
Anything times itself is itself squared
Answer:
coordinates will be (1/2 , -5)
Step-by-step explanation:
when x=4
y= -2(4)+3
y = -8 +3
y = -5
when y=2
2 = - 2x + 3
2-3 = -2x
-1 = -2x
1=2x
x = 1/2
